Starfire. Female. Earth pony.
She’s highly intelligent and observant, but tends to avoid attracting other ponies’ attention and prefers to keep to herself. She tends not to speak unless spoken to, except with friends and some family. She’s got some anger management issues, and she tends to bottle up her feelings about other ponies. She has a passion for comparative linguistics and phonetics, and she tends to start speaking very loudly, almost angrily, when very passionate about what she’s talking about.
As for how her glasses stay on, ask Spitfire.
And oh hey, just noticed I also drew you something from 3 months back. Think I’ve improved since then.
